Where 245 g comes from

USDA FoodData Central: 1 cup of “Milk, buttermilk, fluid, whole” = 245 g. FDC 172225

King Arthur Baking ingredient weight chart (“Buttermilk”): 227 g per cup. Chart

This page uses 245 g (USDA). The two sources differ by 18 g (7.35%): that gap is about how firmly the cup is filled, not an error in either.

Buttermilk weighs 245 g a cup in USDA's data. No buttermilk? Put 1 tablespoon of lemon juice or white vinegar in a cup and fill with milk; wait 5 minutes.

How to measure buttermilk by the cup

Use a liquid measuring jug on a flat surface and read the line at eye level, or weigh it: for liquids a scale is just as quick.
